perl - string comparison in foreach -


the below test check software information on list of ip addresses. program prints version of software running on ips expected.

now, test whether software running on ips identical? how do that?

sub test_check_software_info_on_all_the_ips {      ($self) = @_;      $self->{'machine_ip'} = $self->{'queryobj'}->get_machine_ip();      foreach $ip ( @{ $self->{'machine_ip'} } ) {          $self->{'install_info'} = $self->{'queryobj'}->get_install_info($ip);          info( 'software info of ' . $ip . ' ' . $self->{'install_info'} );     } }

sample output

20160907t141846   info    software info of 1.1.1.1 r-2016-08-27-03 20160907t141846   info    software info of 2.2.2.2 r-2016-08-27-03 20160907t141847   info    software info of 3.3.3.3 r-2016-08-27-03 20160907t141847   info    software info of 4.4.4.4 r-2016-08-27-03

this ask

sub check_matching_info {      ($self) = @_;      $ips = $self->{queryobj}->get_machine_ip;      %info;      $ip ( @$ips ) {         $info = $self->{queryobj}->get_install_info($ip);         push @{ $info{$info} }, $ip;     }      print keys %info == 1 ? "all ips have same install info" : "ips have different install info"; }

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
